Diagnosis and Follow-up Studies in Brain Abscesses Using CT

Abstract

CT is of crucial relevance for the demonstration of intracranial space occupying processes. CT images enable the differentiation between tumor, edema, hemorrhage, cysts and infarcts. There, however, where ring formation characterizes the pathologic process in CT, considerable diagnostic difficulties arise. This is the case in all malignant masses which show central necrosis or cystic tumors which show capsular stain following enhancement as well as infarcts with ring-shaped demarcation of the blood-brain barrier disturbance.
